Hi, I'm new here but while I was researching the sulfite allergy this place came up with some pretty good information but those were really old posts. I take sublingual b-12 whenever I eat anything that causes a reaction and try to avoid all the major sources of sulfites like instant potatoes etc. My allergist doesn't know much about it and hes the best in the area.

Anyway I know I should be taking other vitamin supplements, but I don't know what and how much and all that. So, advice?

That is a question for your doctor. They can run a lab tests (draw blood). The tests you would want in this case are Vitiman Panel and Nutrition Panel. Each person is different, so its the tests that speak. They can tell you if you are in normal range. When I did a vitimin panel a few years back, I was really low on my b-12 in fact I was so low I had to get a shot of it every 2 weeks. Finally worked up to once a month. Just recently got off the shots.

Zinc, Magnesium, Iron, and Molybdenum are the other nutrients that are required for the enzyme pathway that processes sulfites. A good multivitamin may contain enough of these things for you; I agree, however, that testing would be helpful. However, blood tests for magnesium are not accurate; the better magnesium test is the red blood cell magnesium test.
